Cocos2dx InApp爲ios購買

Question

我正在嘗試使用cocos2d x C++在應用程序中集成應用程序購買。我正在使用easyNdk助手進行應用內購買。我的應用程序購買完美適用於我的Objective C應用程序。但對於cocos2d的X是以下行

if ([[RageIAPHelper sharedInstance] productPurchased:productP.productIdentifier]) 

其實值從CPP進來的參數形式完美的文件，並正確顯示其在NSLog的值拋出錯誤，但它總是顯示對象作爲零甚至objetcs打印其在NSLog的

儲值還@try捕捉條件不工作

終於拋出了以下錯誤

請幫助我，我有什麼關係？ 感謝

我.CPP代碼

NDKHelper::AddSelector("HelloWorldSelectors", 
          "SampleSelector", 
          callfuncND_selector(Main::cameFromObjC), 
          this); 

      CCDictionary* prms = CCDictionary::create(); 
      prms->setObject(CCString::create("SampleSelector"), "to_be_called"); 
      prms->setObject(CCString::create(result), "BirdNameKey"); 
SendMessageWithParams(string("SampleSelector"), prms); 

和.mm代碼

- (void) SampleSelector:(NSObject *)prms 
{ 
    NSLog(@"purchase something called"); 
    NSDictionary *parameters = [[NSDictionary alloc]init];// (NSDictionary*)prms; 
    parameters = (NSDictionary*)prms; 
    NSLog(@"Passed params are : %@", parameters); 

    // Fetching the name of the method to be called from Native to C++ 
    // For a ease of use, i have passed the name of method from C++ 
    NSString* CPPFunctionToBeCalled = (NSString*)[parameters objectForKey:@"to_be_called"]; 
    //NSString *str = [NSString stringWithFormat:@"%@",[parameters valueForKey:@"BirdNameKey"]]; 
    NSString *BirdName = [parameters valueForKey:@"BirdNameKey"]; 
    NSString *str = [[NSString alloc]initWithFormat:@"%@",[parameters objectForKey:@"BirdNameKey"]]; 
    NSUserDefaults *d2 = [NSUserDefaults standardUserDefaults]; 
    NSLog(@"%@ , %@ , %@", str,BirdName,[d2 objectForKey:@"product"]); // output is ok for all 
    SKProduct * product = (SKProduct *) [ APPDELEGATE.productDictionary objectForKey:[d2 objectForKey:@"product"]]; 
    [ APPDELEGATE.priceFormatter setLocale:product.priceLocale]; 
    APPDELEGATE.currentProduct =product; 

if ([[RageIAPHelper sharedInstance] productPurchased:product.productIdentifier]) 
     { 
      // check the product purchased or not but app crash at this if statement 
     } 
    [IOSNDKHelper SendMessage:CPPFunctionToBeCalled WithParameters:nil]; 
} 

Answer 1

我也有這個問題，我解決了它。 在您的IAPhelper中。毫米

只有具備以下行

_purchasedProductIdentifiers = [[NSMutableSet alloc] init]; 

做替換該行

_purchasedProductIdentifiers = [NSMutableSet set]; 

如下圖所示

- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers { 

    if ((self = [super init])) { 

     // Store product identifiers 
     _productIdentifiers = productIdentifiers; 

     // Check for previously purchased products 
//  _purchasedProductIdentifiers = [NSMutableSet set]; 
     _purchasedProductIdentifiers = [[NSMutableSet alloc] init]; 
     for (NSString * productIdentifier in _productIdentifiers) { 
      BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier]; 
      if (productPurchased) { 
       [_purchasedProductIdentifiers addObject:productIdentifier]; 
       // NSLog(@"Previously purchased: %@", productIdentifier); 
      } else { 
       // NSLog(@"Not purchased: %@", productIdentifier); 
      } 
     } 

     // Add self as transaction observer 
     [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; 

    } 
    return self; 

} 

Answer 2

我看到兩個（潛在的）問題與您的代碼，

首先

CCDictionary* prms = CCDictionary::create(); 

請注意，初始化數據對象這種方式並不能保證它不會被釋放，當您嘗試訪問它後面的代碼（在其他功能上專門）

所以，試試這個代替，

CCDictionary* prms = new CCDictionary(); 
prms->init ... (the initialization) 

但請注意，通過這樣做，現在您有責任在完成該操作後刪除此對象。另外，我不確定「setObject」方法的實現，如果它保留了對象，那麼我相信這一步將不是必需的，但我不確定是否必須檢查它！

其次

NSDictionary *parameters = [[NSDictionary alloc]init];// (NSDictionary*)prms; 
parameters = (NSDictionary*)prms; 
NSLog(@"Passed params are : %@", parameters); 

我覺得這是在鑄件（或我可能是錯的）

我建議你的問題做這樣的事情

(NSDictionary *)nsDictionaryFromCCDictionary:(cocos2d::CCDictionary *)ccDictionary { 
if (ccDictionary == NULL) { 
    return NULL; 
} else if (ccDictionary->allKeys() == NULL) { 
    return NULL; 
} else if (ccDictionary->allKeys()->count() <= 0) { 
    return NULL; 
} 

cocos2d::CCLog("1"); 

NSMutableDictionary *nsDict = [NSMutableDictionary dictionaryWithCapacity:ccDictionary->allKeys()->count()]; 

cocos2d::CCLog("2"); 

for (int i = 0; i < ccDictionary->allKeys()->count(); i++) { 
    cocos2d::CCLog("3"); 

    cocos2d::CCObject* obj = ccDictionary->objectForKey(((cocos2d::CCString *)ccDictionary->allKeys()->objectAtIndex(i))->getCString()); 
    NSObject* nsObject; 
    if(isKindOfClass(obj, cocos2d::CCDictionary)) 
    { 
     nsObject = @"Dictionary"; 
    } 
    else if(isKindOfClass(obj, cocos2d::CCArray)) 
    { 
     nsObject = @"Array"; 
    } 
    else if (isKindOfClass(obj, cocos2d::CCString)) 
    { 
     const char* cstring = ((cocos2d::CCString*)obj)->getCString(); 
     nsObject = [[[NSString alloc] initWithBytes:cstring length:strlen(cstring) encoding:NSUTF8StringEncoding] autorelease]; 
    } 
    else if (isKindOfClass(obj, cocos2d::CCInteger)) 
    { 
     nsObject = [NSString stringWithFormat:@"%d", ((cocos2d::CCInteger*)obj)->getValue()]; 
    } 
    else 
    { 
     nsObject = @"Unknown Object"; 
    } 
    [nsDict setValue:nsObject forKey:[AnalyticXStringUtil nsstringFromCString:((cocos2d::CCString *)ccDictionary->allKeys()->objectAtIndex(i))->getCString()]]; 
} 

return nsDict; 

}

我粘貼了以上代碼>>>https://github.com/diwu/AnalyticX/blob/master/Add-To-Your-Own-Project/AnalyticXStringUtil.mm

嘗試接收字典作爲CCDictionary，並檢查此對象是否有效（因爲mm可以有C++和目標c代碼，所以這不會是一個問題）然後創建NSDictionary後，嘗試打印它。我希望這次不會給你錯誤。
